Airbag control unit with part number 98820-3LM1A

What does the airbag control unit 98820-3LM1A do?

The airbag control unit 98820-3LM1A is the central component of the restraint system (SRS) in Nissan. It evaluates the sensors, decides in a crash on airbags and seatbelt pretensioners, and monitors the system continuously. After an accident, it stores crash data and then locks itself.

Detected faults are shown via the airbag warning light in the instrument cluster, so that you can read the condition of the system.

Why does the control unit 98820-3LM1A fail?

On the 98820-3LM1A, the most frequent cause of failure is stored crash data, even if no airbag has fired. An ordinary diagnostic tool cannot erase this data. Other causes are aged components, cold solder joints, moisture, corrosion and voltage spikes.

• aged components
• cold solder joints
• moisture and corrosion at plug connections
• voltage spikes

Airbag24 erases crash data as part of the repair.

How can you tell that the 98820-3LM1A is defective?

On the 98820-3LM1A, you recognise a defect by an error message in the instrument cluster, the airbag warning light, a missing connection to the diagnostic tool and a fault memory that cannot be cleared.

• Airbag warning light lights up permanently or intermittently
• Error message in the instrument cluster
